Method Detail

duplicate

public IntArrayList duplicate()

Description copied from interface: ReadOnlyIntStack

Duplicates the current stack.

Specified by:

duplicate in interface ReadOnlyIntStack

Returns:

a new stack with the same states that the current one.

add

public void add(int value)

Adds a value on top of the list.

Parameters:

value - the value to add.

removeLast

public void removeLast(int number)

Removes the last values on top of the stack.

Parameters:

number - the number of values to remove.

removeLast

public int removeLast()

Removes the last value on top of the stack and returns it.

Returns:

the value on top of the stack.

See Also:

removeLast(int)

last

public int last()

Description copied from interface: ReadOnlyIntStack

Returns last inserted (i.e. the current) state.

Specified by:

last in interface ReadOnlyIntStack

Returns:

the current state.

clear

public void clear()

Clear the whole list.

get

public int get(int index)

Description copied from interface: ReadOnlyIntStack

Returns the state number at the given position.

Specified by:

get in interface ReadOnlyIntStack

Parameters:

index - the position.

Returns:

the state number.

set

public void set(int index,
                int value)

Changes the value at index index by a new one. This call assume that the value at index index if already allowed so it doesn't ensure a capacity, you can use add(int) instead.

Parameters:

index -

value -

size

public int size()

Description copied from interface: ReadOnlyIntStack

Returns the number of states in the stack.

Specified by:

size in interface ReadOnlyIntStack

Returns:

the number of states in the stack.

isEmpty

public boolean isEmpty()

Description copied from interface: ReadOnlyIntStack

Returns true is the number of states in the stack is zero.

Specified by:

isEmpty in interface ReadOnlyIntStack

Returns:

true if the stack is empty, false otherwise.

toString

public String toString()

Overrides:

toString in class Object
